We can provide you with and install the latest version of ACT! and convert your ACT! 6 Database.  If you have multiple ACT! 6 databases we can merge them and convert them as well.  We also provide diagnostic services as well as troubleshooting for things like Synchronization, reports and lookups. 

Not sure if the system you're running ACT! 6 on is ready for ACT! 2008 or newer?  We can do an assessment for you as well.
